The Boomershines Conquer the World's Tallest Lift Lock

The Boomershines are back, and this time they're aiming for a whopping 50 nautical miles and eight locks in a single day! Their trusty starboard engine, however, seems to have developed a bit of a smoking habit. After a quick consultation with the mechanic (who assures them it's just "burning off" some spilled fuel – sure, Jan!), they press on. The day is filled with tight squeezes, charming houses, and some truly perplexing channel markers. The main event? The world-famous Peterborough Lift Lock, a giant bathtub that hoists their 40-ton boat 60 feet in the air! It's a marvel of engineering, complete with ducks and kayakers along for the ride. But the adventure doesn't stop there. They encounter shallow waters, a university that looks like it's straight out of "Planet of the Apes" (according to Mark, anyway), and a race against the clock to make it through the final lock before closing time. Will they succeed, or will they be spending the night on a lock wall? You'll have to watch to find out!
